Problems solved by technology

The information obtained by traditional monitoring methods is limited, and it is impossible to predict and warn in advance of hidden dangers in the operation of waterwheel indoor equipment and rising water levels, and can only be dealt with passively. In the event of a failure, sufficient emergency response time cannot be reserved; secondly, there is a large gap between the traditional monitoring method and the requirements of unattended and smart power plant construction. The real-time evaluation and analysis basis of the equipment operating status system in the vehicle room cannot effectively realize pre-intervention and control the development of the situation
The existing operation trend analysis methods in the industry have the disadvantages of lagging analysis results, inability to realize real-time prediction and early warning

Abstract

The invention provides a water flooded waterwheel chamber early warning method and system based on a knowledge graph. The method comprises the steps of acquiring historical operation time sequence data of a waterwheel chamber system; analyzing the top cover water level change trend of the waterwheel chamber according to the historical operation time sequence data; analyzing the occurrence probability of various faults of the waterwheel chamber system according to the top cover water level change trend; and calling corresponding processing measures from a fault management knowledge graph according to the occurrence probability of various faults to carry out early warning prompt. Through the mode, the fault type and reason can be autonomously judged while early warning is carried out in advance, and enough response time is provided for timely fault processing.

Description

technical field [0001] The present application relates to the technical field of safety protection of hydropower stations, and in particular, to a method and system for early warning of flooded water tankers based on knowledge graphs. Background technique [0002] During the operation of the hydroelectric generating set, the safe operation of the waterwheel room is very important, and the biggest threat to it is the accident of flooding the waterwheel room. The information obtained by traditional monitoring methods is limited, and it is impossible to predict and warn in advance of hidden dangers in the operation of waterwheel indoor equipment and rising water levels, and can only be dealt with passively. In the event of a failure, sufficient emergency response time cannot be reserved; secondly, there is a large gap between the traditional monitoring method and the requirements of unattended and smart power plant construction. The real-time evaluation and analysis basis of t...
